Product catalog summary

Safety Notes and Technical Support
Installation, maintenance, and commissioning of the Rotonivo® level limit switch should be conducted by qualified personnel. The manual must be followed, with attention to warnings about electric shock and material damage risks. For technical support, contact UWT GmbH or your local supplier.

Introduction
The Rotonivo® is an electromechanical level limit switch for monitoring bulk goods levels, suitable for industries like building materials, food, plastics, timber, chemical, and mechanical engineering. It can be mounted laterally or from the top of a container, with probe lengths up to 10 meters.

Function
The device uses a measuring vane driven by a synchronous motor. When covered by material, the motor stops, indicating a 'covered' status. A fail-safe alarm option detects faults like motor or gear failure.

Technical Data
The RN 3000 and RN 6000 series offer various configurations, including explosion-proof options, supporting different power supplies and signal outputs, with adjustable delay and fail-safe alarm features. Materials include stainless steel and aluminum, with specific temperature and pressure specifications.

Approvals and Options
The devices have Ex-approvals for hazardous areas and can be customized with options like sliding sleeves and different vane types.

Mounting and Electrical Installation
Instructions emphasize correct setup for proper function and safety.

Signal and Alarm Output
Devices offer switchable signal outputs with fail-safe high/low settings and adjustable delays.

Setting and Sensitivity
Guidance is provided on setting device sensitivity for accurate level detection.

Maintenance
Regular maintenance is recommended for device longevity and reliability.

Notes for Use in Hazardous Locations
Special considerations ensure compliance with safety standards in hazardous environments.

Disposal
Proper disposal instructions ensure environmental compliance.

Overview
The document provides technical information and instructions for the Rotonivo® Level Limit Switch Series RN 3000 / 6000, including specifications, operating conditions, approvals, and options for installation and use.

Specifications
The RN 3000 and RN 6000 series are designed for various temperature ranges, with process connections in aluminum and stainless steel. The devices are equipped with ball bearings and friction clutches to protect the gear unit.

Operating Conditions
The devices operate in ambient temperatures from -40°C to 1,100°C, depending on the version. They are not recommended for environments exceeding 900°C unless specific conditions are met.

Mechanical and Process Specifications
Maximum mechanical torque and process pressure vary by model and temperature. Protective measures are recommended for high-load scenarios.

Approvals and Safety
The devices have certifications like ATEX and IEC-Ex for hazardous locations, complying with safety and environmental standards, including SIL 2 and RoHS.

Options and Accessories
Optional features include weather protection covers, sliding sleeves, signal lamps, and various plug types.

Installation and Maintenance
Proper installation is crucial for maintaining process pressure and chemical resistance, with guidelines for mounting location and mechanical load limits.

Mounting Instructions
The housing can be rotated after mounting, with specific instructions for sealing and precautions for dismounting and service.

Electrical Installation
Emphasizes following local regulations, with detailed instructions for electrical connections, including fuses, RCCB protection, and grounding.

Safety Instructions
Includes grounding to avoid static charging and proper installation of field wiring cables, with additional instructions for hazardous locations.

Signal and Alarm Output
Describes configurations, including micro switches, relays, and switching logic (FSL or FSH) based on application.

Settings and Sensitivity
Spring sensitivity can be adjusted based on material type, with minimum density values for normal function provided.

Maintenance
Ensure no live circuits, dust deposits, or rain during maintenance, with frequent checks for mechanical damage and sealing integrity.

Hazardous Locations
Devices are suitable for various dust and gas zones, with specific EPL and category ratings.

Disposal
Recycling should be done by specialized companies, with materials detailed in the technical data section.

Level limit switch Series RN 3000 / 6000 Technical information / Instruction manual Fail safe alarm With the option fail safe alarm it is possible to recognize a fault of the unit in time and to initiate an alarm relay. The following faults are observed: A measuring vane is driven by a synchronous motor. The bearing of the motor inside the housing allows it to swing. The motor is fixed to a switching lug. If the vane is uncovered, a spring pulls the motor and switching lug to the left position (figure 1). When material covers the vane and thus stops the rotation, the motor and switching lug swings...
